[John Tyndall, in the course of an article in Longman’s Magazine, reprinted in The Theosophist, expresses his belief that: “Man is prone to idealization. He cannot accept as final the phenomena of the sensible world, but looks behind that world into another which rules the sensible one. . . . Number and harmony, as in the Pythagorean system, are everywhere dominant in this underworld.” To this H. P. B. appends the following footnote:]

This paragraph would be in its right place in the best text on Occult Doctrine. The latter is based entirely upon numbers, harmony, and correspondences or affinities.
